photo uploading: initialize date field with date of the file

[BertrandJ]

I have developped an appsheet app to store my personal photos. 

To load each of them I need to open a form, then load the file, and fill in a date field manually, to store the moment this picture was shot. Is there anyways to have this date field pre filled with either the date the picture was shot, or at least the creation date of the file?

Thanks for your help
